Hi there, Just upgraded to a 40" Sony from 32" Samsung and when I connect throught the HDMI Picture is perfect but regularly the picture drops and then refreshes so you get a second of black screen. Its as if the tv is polling to look for an input. First I thought it was a problem with the VM signal but after re-connecting Samsung its fine. Anybody got any words of wisdom? Think it must be the TV but not sure what the problem is. Been throught the menus repeatedly ad can't find a thing.
